If you're up for it then you can remove the second slot's display connectors, the stock heatsink/fan, and then cut the second slot off the GPU and install a water block and only use the top 3 display outputs per GPU. However, this voids the living crap out of your warranty and requires custom watercooling.

There are some boards that design the PCIe layout with a PCIe x1 card to the left of the primary PCIe x16 slot. This is a minor nitpick issue on my part (kind of like the CMOS battery placement that y'all always nail me for), but not a major detractor from the board. It was a very nice board that tested well...

Micro Center, which has many other boards priced extremely well, has this one priced $63 more than most other retailers. Oddly enough, they've also incorrectly listed it as the "ASUS Z97", leaving out the"-WS". Would dig picking it up from them, but not at their current pricing.
